關於此翻譯

思科已使用電腦和人工技術翻譯本文件，讓全世界的使用者能夠以自己的語言理解支援內容。請注意，即使是最佳機器翻譯，也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責，並建議一律查看原始英文文件（提供連結）。

簡介

本文檔說明了一種同時包含網關到網關和遠端使用者功能的IPsec配置。使用擴展身份驗證(Xauth)，裝置通過預共用金鑰進行身份驗證，使用者通過使用者名稱/密碼質詢進行身份驗證。

必要條件

需求

本文件沒有特定需求。

採用元件

本文中的資訊係根據以下軟體和硬體版本：

  • PIX防火牆版本6.3(3)

  • Cisco VPN使用者端版本3.5

  • 適用於Windows的Cisco安全ACS版本2.6

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

背景資訊

在本示例中，存在從遠端PIX到中心PIX的網關到網關IPsec隧道。此隧道加密從遠端PIX後面的網路10.48.67.x到中心PIX後面的網路10.48.66.x的流量。Internet上的PC可以通過集線器PIX形成到網路10.48.66.x的IPsec隧道。

若要使用Xauth功能，您必須首先設定基本驗證、授權和計量(AAA)伺服器。使用crypto map client authentication命令通知PIX防火牆在網際網路金鑰交換(IKE)的第1階段使用Xauth（RADIUS/TACACS+使用者名稱和密碼）質詢來驗證IKE。如果Xauth失敗，則不會建立IKE安全關聯。在crypto map client authentication命令語句中指定aaa-server命令語句中指定的相同AAA伺服器名稱。遠端使用者必須運行Cisco VPN客戶端版本3.x。或以後。

注意：思科建議您使用Cisco VPN客戶端3.5.x或更高版本。VPN客戶端1.1無法使用此配置，並且不在本文檔的討論範圍之內。

注意：Cisco VPN Client 3.6及更高版本不支援des/sha的轉換集。

如果您需要在不使用Xauth的情況下還原組態，請使用no crypto map client authentication命令。預設未啟用Xauth功能。

註：加密技術受出口管制約束。您有責任瞭解與加密技術出口相關的法律。如需詳細資訊，請參閱出口管理局首頁 leavingcisco.com 。如果您有任何有關出口管制的問題，請傳送電子郵件至export@cisco.com。

注意：在PIX防火牆版本5.3及更高版本中，引入了可配置的RADIUS埠。某些RADIUS伺服器使用RADIUS連線埠而不是1645/1646（通常為1812/1813）。 在PIX 5.3及更高版本中，可以使用以下命令將RADIUS身份驗證和記帳埠更改為預設1645/1646以外的埠： 

aaa-server radius-authport #
aaa-server radius-acctport #

設定

本節提供用於設定本文件中所述功能的資訊。

附註：使用 debug 指令之前，請先參閱有關 Debug 指令的重要資訊。

必須在兩台IPsec路由器（對等路由器）上運行這些調試。 必須在兩個對等體上清除安全關聯。

  • debug crypto isakmp — 顯示階段1期間的錯誤。

  • debug crypto ipsec — 顯示階段2期間的錯誤。

  • debug crypto engine — 顯示來自加密引擎的資訊。

  • clear crypto isakmp sa — 清除第1階段安全關聯。

  • clear crypto ipsec sa — 清除第2階段安全關聯。

  • debug radius [session |全部 | user username] — 在PIX 6.2中可用，此命令記錄RADIUS會話資訊以及已傳送和已接收RADIUS資料包的屬性。

  • debug tacacs [session|user <user_name>] — 在PIX 6.3中可用，此命令記錄TACACS資訊。

  • debug aaa [authentication|authorization|accounting|internal] — 在PIX 6.3中可用，顯示AAA子系統資訊。

從集線器PIX調試

注意：請注意，有時當IPsec交涉成功時，並非所有偵錯都因為Cisco錯誤ID CSCdu84168(僅限註冊客戶)而顯示在PIX上，該錯誤ID是內部Cisco錯誤ID CSCdt31745(僅限registered客戶)的副本。 截至編寫本檔案時尚未解決這個問題。

注意：有時，來自VPN客戶端的IPSec VPN可能不會在PIX上終止。要解決此問題，請確保客戶端PC沒有任何防火牆。如果存在防火牆，請檢查UDP埠500和4500是否已禁用。如果是這種情況，請啟用IPSec over TCP或取消阻止UDP埠。
